I doubled up and overlapped a bunch of the existing panda. Then I sat in there with the light off this morning and used 2 rolls of duct tape and went apeshit on all of the tiny little rays of light. I think I am good now.

It is funny because I have seen some setups that had terrible light leakage and the guys would walk in and out of the room all day...They never had any hermie issues..I wonder is some genetics are more resistant to it than others.
